4626. When any spirit is approaching, even though still a long way off and out of sight, his presence is detected, as often as the Lord allows it to be, from a certain kind of spiritual sphere. From that sphere one recognizes what his life is like, what his affection is like, and what his faith is like. Angelic spirits with keener perception know from his sphere countless things about the state of his life and faith, as has been demonstrated to me many times. When it pleases the Lord these spheres are also converted into odours; one smells quite distinctly an actual odour. The reason those spheres are converted into odours is that odour corresponds to perception and that perception is so to speak spiritual odour, from which also [natural] odour descends. But see what has been brought forward already on these matters - regarding spheres, in 1048, 1053, 1316, 1504-1519, 1695, 2401, 2489, 4464; perception, in 483, 495, 503, 521, 536, 1383, 1384, 1388, 1391, 1397, 1398, 1504, 1640; and odours produced by these, in 1514, 1517-1519, 1631, 3577.
